I don´t see the ATM words in the requirements, so there could be other rules. Cheers my friend. Ending this discussion from my side.

Of course the Kata is not meant not change, agree on that. But training also for readable & maintable code is much better than saving 3 lines of code. If you have worked in some companies you might agree with me. The kata doesnt say anithing, but it mention "rules" and rules are likely meant to change, different from a kata that explicity say "add two numbers" and nothing else. Do you see my point? Its a programmer challenge to identify requisites that likely to change, like this. That's what I mean, not that the code is wrong.

when you solve a problem you should also consider how probabl is that rules change over the time, and do your on future changes :)

I love this ppl, they just make my day

Not even chatgpt dared so much!!

too complex man! difficult to read if you donno the pin conditions

It is just short. But not so good if pin "condition" changes with by adding complex ones.
